MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 788,226, dated April25, 1905. Application filed geptember 19, 1904. Serial No. 224,978.

To all whmn, it may concern:

Be it known that I, WARREN SWEET, a citizen of the United States ofAmerica, and a resident of Fort Wayne, in the county of Allen and Stateof Indiana, have invented certain new and useful Improvements inMechanical Movements, of which the following is a specification,

This invention relates to improvements in mechanical movements; and theobject thereof is to provide gearing for converting continuous rotarymotion into oscillating motion, the oscillating member to be actuated ata lower rate of speed relative to that of the driving orcontinuously-rotating member. I accomplish this object by theconstruction illustrated in the accompanying drawings, in which Figure 1is an elevation showing the mechanism of the invention partly invertical central section. Fig. 2 is a plan of the same, partly cut away.Fig. 3 is a front elevation of the intermediate member. Fig. 4: is anelevation of the intermediate member viewed from a point at right anglesto that of Fig. 3. Fig. 5 is a detail showing in partial section theconstruction of the driving-shaft coupling.

Similar numerals of reference indicate corresponding partsthroughout'the several views.

Referring now to the drawings, 1 is a supporting-casting, which isarranged upon a suds vessel 2 and is fixed upon the lid 3 thereof. 41 isa driving-shaft, mounted in a hearing 5, which is a part of saidcasting, and 6 is a tumbling-shaft having a connection with the shaft 4by means of which the shaft 6 is driven and at the same timeaccommodated so as to be free to swing vertically. This connectionconsists of a sleeve 7, rigidly fixed 4 upon the inner end of the shaftl and extending therefrom sufficiently to receive one end of the shaft6, and a pin 8 is fixed in said sleeve and extends through a suitableopening 9 in said shaft 6, the opening being of a form which will admitof a swinging motion of said shaft 6.

10 is a guide having a vertical slot 11 therein through which the shaft6 extends and in which the latter is adapted to rotate and at the sametime move vertically.

12 is an intermediate driving member mounted upon a stud 13 and havingupon its flange 14 an internal rack 15. An elongated lug 16 is arrangedexternally upon said flange and has a curvature conforming therewith,and a series of radially arranged pins 17 extend from said lug and aredonnected at their outer ends by a curved bar 18. An oblong guard 19,having curvature corresponding to the member 12, is attached thereto andsurrounds the lug 16, leaving an intervening space 20 entirely aroundsaid lug and within the flange 21 of said guard, suitable to receive theinner end of the shaft 6. A driving-pinion 22 is mounted upon said shaft6 and is adapted to 5 engage with the pins 17 and actuate the member 12.

A driven shaft 23 is mounted vertically in a suitable sleeve-bearing 24,which is a part of the casting 1 and which extends down- 7 ward throughthe lid 3 of the vessel 2. A pinion 25 is fixed upon the upper end ofthe shaft 23 and meshes with the rack 15, by which the former isactuated.

26 is an agitator arranged in connection with the lower part of theshaft 23.

Another feature of this invention consists in the manner in which thecasting 1 is in part secured to the lid 3. Reference is had to the bolt27, which extends upward through the lid 3 and stud 13 and has a nut 28driven on its upper end, which secures a washer 29, the latter beinginterposed between the nut and the top of the'stud 13. It will beobserved that the washer overhangs the member 12 and 5 prevents it fromrising, and at the same time the bolt serves to hold the casting firmlyupon the lid 3. Bolts 30 are also used to assist in securing the casting1 to the lid.

In the operation of this invention the shaft 9 4 is rotated by anysuitable means, such as a wheel 31, and thereby the shaft 6 and. pinion22 are actuated. As the pinion 22 revolves the member 12 will be turnedupon the stud 13 and the inner end of the shaft 6 will glide in thespace 20 between the flange 19 and lug 16, so that the pinion 22 willoperate alternately over and under the said series of pins, and thusdrive the member 12 in an oscillating fashion, The hub 22 of the pinion22 rides on the bar 18, while the shaft 6 is in its uppermost position.It is obvious that because of the oscillating motion of the member 12the agitator will become oscillating accordingly. V

The top of the member 12 aflords a convenient plane for the display ofadvertising matter, which may be placed or formed thereon in anysuitable manner, and said member being in the form of a disk will serveas a rest for the mechanism when the lid 3 is opened by coming intocontact with a suitable plate 33 on the edge of the vessel 1.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In mechanism of the class described, a casting having a stud;suitable driving mechanism mounted in said casting; an intermediatedriving member mounted upon said stud and adapted to oscillate thereon;a suitable support for said casting; and a bolt connected with saidsupport, extending through said stud, and having means in connectionwith its upper end to retain said casting upon said support and alsoprevent said intermediate member from rising.

2. In mechanism of the class described, a casting; a suitably-hingedsupport therefor;

driving mechanism in connection with said casting and comprising in partan intermediate driving member having a circular top, the saidintermediate member serving also as a rest for the mechanism when swungback.

3. In mechanism of the class described, a supporting-casting; a drivenshaft mounted in said casting and a pinion mounted thereon; anintermediate driving member mounted on said casting, having an internalrack adapted to engage and drive said pinion, the said d riving memberhaving a flange and serving as a shield for said rack and pinion; andsuitable driving mechanism in connection with said intermediate memberto actuate the same.

4. In mechanism of the class described, a supporting-casting; a drivenshaft mounted in said casting and a pinion mounted thereon; anintermediate driving member having an internal rack adapted to engageand drive said pinion and an external series of pins radially disposed,the said member having also a closed top and depending flange; adriving-shaft and tumbling-shaft loosely coupled together to permitvertical play of the latter; and the pinion mounted on thetumbling-shaft and engaged with said series of pins.

In testimony whereof I afiix my signature in presence of two witnesses.
